How To: Changing Diff Oil

[eXc]

Topic: Diff Oil Replacement

Car: R32 GTST / RB20DET

Difficulty: 2/10

Hey Guys,

Just a very quick how to. Just to show everyone how easy it is to do, don't bother paying a shop to do it

Cheers

Chris

Tools Required (Image 1)

- 1/2 drive Ratchet + Extenders + Universal to make life easy.

- Possibly a pipe to use as extra leverage

- Diff Oil - I use Castrol LSX 90 and it used about 2L I think from memory 5L cost me $50ish I think

- Some kind of pump. You can't pour it in. You need a pump. This one cost me $10 at repco

- Jack + car stands or ramps or a pit (you need to get under the car)

- Drain Container 2litre minimum

Step 1

Get the car off the ground, make sure it's secure and not going to fall

Step 2

(May be better doing step 3 first to check you can get the filler bolt undone!!)

Undo the drain bolt (bottom of diff) (image 2)

Step 3

Undo the filler bolt (Side of diff) (Image 2)

Step 4

Once fully drained, put the drain bolt back in (don't get them mixed up! - Image 3)

Step 5

Start pumping the new oil into the Diff. It takes ages, atleast it did with my pump. My arm got very sore due to small area to move and thick oil.

Fill until the oil comes out the side of the filler hole.

Step 6

Replace filler bolt

Step 7

Clean up mess, check bolts are tight. Go Drive

While you're under there, check that the driveshaft (halfshafts) bolts are tight, and the diff mounts too.

would this be the same for R33 aswell?

[MANWHOR3]

yes, the most difficult and time consuming things are jacking the car and putting it on stands to make it safe, and undoing the bolts. they can be quite tight sometiems.

you dont need a pump.

Cut a length of hose long enough to go from the rear wheel arch to reach the diff.

Then feed the hose over the tyre through the suspension, and into the diff filler hole on the side.

Now place a funnel into the hose and fill it up

I'd suggest doing 3 before 2..

if for some reason you can't undo the filler plug.. your in some serious sticky diff oil with no way to fill it up..

just an observation..

hmmm true. I'll edit

yips i found it a few days ago, thanks heaps anyways tho

damn that filler bolt is a real whore to undo

[QUIKBLADE]

Although I haven't even looked... But I imagine it would be similar (?)

I have a Cefiro eg: R32GTST running gear/driveline etc and a 2 way LSD... I will post up pics when I change the oil, but any ideas if the filler hole/drain plug would be in a similar position?
